PAPER DRIER.

Application filed January 26, 1925. Serial No. 4,78%

To all whom it may concern:

Be it known that I, CHARLEs W. SHARTLE,

a citizen of the United States, residing at ll liddletown, in the county of Butler and State ofOhio, have invented certain new and useful Improvements in Paper Driers, of which the following is a specification, reference being had "therein to the accompany ing drawings.

This invention relates to paperdriers.

The main object attained in the inventionj is a drying apparatus-adapted to receive the paper web from a paper-forming machine, as a fore drier machine, and in which the drying process will be facilitated by passing of the web of paper in a serpentine path over a plurality of sets of drier rolls or cylinders arranged in units and in series, with the opposite sets of a unit inclined at an angle one to another and with triangularshaped drying spaces interposed between adjacent sets of the unit to facilitate the drying process,the rolls of each set of the apparatus being 'gear-entrained one with another and driven from a common shaft, the

apparatus as a whole. being/supported in a suitable frame which serves" to coordinate all the units in a unitary machine.

The apparatus, as a whole, is more com-- pact and stands higher than paper driers of the ordinary construction, that is to say, paper driers arranged in an extended horizontal plane. Thus the improved apparatus is confined to lessfloor space and, because "of its height, a greater volume "of air iscaused to circulate over and between the drying rollers and over both surfaces of the paper web as it travels over the apparatus, the action of the air at the higher points of the machine also being more efi'ective in the drying action on the paper because of its relatively higher temperature than at the lower elevations.

' lln the accompanying drawings:

1 is a side elevation of two adjacent units of the machine;

Fig. 2 is a detail view of driving the gdriermolls;

Fig. 3 is a broken plan View of Fig. 1 g

Fig. 4 is a detail of a drier roll.

shownin Fig. 1, each unitot the apparatus consists of an lli-shaped'frame structure in which is supported, in each of the the gearing for opposite frame memhers l thereof, a double series of drier rollsZ comprising a set arranged in planes parallel one with another and inclined to the vertical with. the rollers of, the opposite series alternated one with another in parallel horizontal planes, therollsof the opposite sets being inclined, as a result of the A-shaped structure, one toward the other upwardly thus forming a similarly shaped drying space between the opposite series of rolls.

, As illustrated in Fig. 2, the drier rolls are gear-entrained one with another by means of equal gears'3, the driving action being alternated from one roll to another of the 'coacting series with the result that all the rolls of one series will be rotated in clock: wise direction and allthe rolls of the opposite series will be rotated in counter-clockwise direction and the paper web 4:,traversing the rolls in their alternate arrangement, will move in a serpentine path I from the lowest to the highest'roll of one set and thence to the highest roll and from the highest to .the lowest roll of the adjacent ofv the unit.

Operating movement is transmitted to each set of rolls by means of a gear 5 con nected to a source'of power (no-t shown) means ofshafts 6.

Steps? anda handrail 8 are'provided on,

one side of the apparatus to-make all parts of the mechanism. conveniently accessible and also to provide convenient means of observation of the paper during the drying process. p

1 From thearrangement of the rollers of each unit of" the apparatus one with respect to another and also the relation of one unit to another, it will be observed that relatively large areas A occur between the rollers of each unit and similar spaces B between adjacent units. The air, which is'usually artificially heated, acts on both sides of the paper in these spaces with the result that the drying process will be rapid and large and effective observation of tile peperwhieh is thus eftorded a ong the entire apparatus and also the con enient sieeessiliiility sfiorded to all parts of the mechanism.

Having described any inventioml claim:

1. A paper drier including in oombination, a plurality of sets of drier rolls erreuged in planes inclined upwardly one toward the other comprising a unitary serpentine path contiguous to said area.

2. A. paper drier including in combinetion, a plurality of sets of drier rolls arranged in planes inclined upwardly one to- Ward. the other comprising unitary structure, an air area, being formed "Within the angle of said structure, each set comprising opposite series oi rolls enged iu planes parallel one to the other, the rolls of one serie being disposer izrp es intermediate the rolls of the other s and operable in :i direction. opposite to that of the rolls of said other series, whereby a. web of paper adopted to traverse the rolls of said structure in a, serpentine path contiguous to said ares.

3; A paper drier including in combine tion, as plurality of units oi paper drier rolls arranged in tandem Formation, eech unit eor prising a plurality setsotf said rolls arranged in planes inmlned upwardly one toward another, thus forming sir areas within each unitary structure and between said units, each set comprising opposite series of rolls arranged planes perallel issuer:

one to the other, the rolls of one series being operable in a direction opposite to that of the rolls of the other series, whereby a. Web of paper is adapted to traverse the rolls of said structure in a. serpentine path contiguous to said arses, V

4.. A paper drier including in combination, a plurality of units of paper drier rolls arranged in tandem formation, eueh unit comprising a plurality of sets of said rolls arranged 111 planes inclined upwardly one" toward another, thus forming air areas Within each unitary structure end betweel said units, each set comprising opposite series of rolls arranged in planes parallel one to the other, the rolls of one series being operable in e direc*ion opposite to that of the rolls of the other series, whereby it Web of paperjs adapted to traverse the rolls of said structure in a serpentine oeth contiguous to said area's, ing said angular area at the sides and within each unitary structure and at the sides and bottom between said units.

5. A paper drier including in combination, a plurality of units of paper, drier rolls supported in :h-sh epecl structures and arranged in tandem rniation one unit "etive to ano'her, thus forming sir ereas within and between the units, each unit oomprising a phlmlity of sets of drier rolls, eseh set comprising opposite series of rolls arranged in planes parallel one to the other, the rolls of one series being operable in direction opposite to that of the rolls of ti other series, whereby a Web of paper stdepted tov treverse the rolls of said structure in a serpentine path contiguous to said srsas.

In testimony whereof, l etiix my signature.
